AEA RPQ 503
500 Series Mic Preamp & EQ
Your Favorite Ribbon Preamp—Now in 500 Series
The RPQ503 is the next evolution in AEA’s trusted lineage of high-impedance, high-gain preamplifiers.
Based on the 3rd Generation circuit design of our celebrated RPQ3, the RPQ503 brings the same rich
and natural sound to the 500 Series Format. Featuring a powerful combination of ultra-low noise,
low-distortion op-amps, ultra-high 68KΩ input impedance, and 85dB of clean gain, the RPQ503
delivers exceptional clarity and detail. More than just a preamp, the RPQ503 also includes the
expanded EQ section of the RPQ3, with boost and cut controls for both low and high end, on custom,
compact, dual-concentric potentiometers.
At once open and transparent but equally responsive and dynamic, the RPQ503 is a versatile tool for
the front end of any signal path.
